SEAL.

Specification of Letters Patent.

Patented June 20, 1916.

Application filed April 13, 1915. Serial No. 21,012.

To all whom t may concern l:

' Be it known that I, RAYMOND H. JUNE, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented an Improvement in"Seals, of which the following is aspecification.

This invention relates to seals and more particularly a seal adapted forluse on the doors of railroad rolling stock, said seal being of thattype wherein a metal strip'is y passed through the staple of the doorand strip shown in locked position.

secured at its ends so that the same would have to be broken in order togain access to the car, thereby indicating whether or not the car hasbeen entered any time subsequent to the sealing of the door.

The object of my invention is to provide simplified and more efficientconstruction for rigidly interlocking the ends of the seal andvpreventing separation thereof after they have once been broughttogether, and

to provide improved means for preventing insertion of tools orappliances to thereby prevent picking of the lock. 4

vThe inventive idea involved is capable of receiving a variety ofmechanical expressions, one of which, `for the purpose of illustratingthe invention, is shown in the accompanying drawing, in which- Figure 1is a perspective view of the ends of the strip constructed in accordancewith the invention. Fig. 2 is a vertical longitudinal sectional view ofthe ends of the Fig. 3 is a section on the line 3-3 of Fig. 2. Fig. 4 isa view similar to Fig. 2 showing the parts previous to being locked.Fig. 5 is a top plan view of the strip before being bent into the formof a loop to lock the ends together. Fig. 6 is a plan view in blank ofthe strip, the dotted lines showing the manner of folding the same. Fig.7 is a top plan view of the housing partly broken away and shown insection.

Referring more particularly to the accompanying drawing, in which likereference characters designate similar parts, the numeral 10 indicatesthe body portion of the device which is made of an elongated strip ofsheet metal, preferably tin. One end of the strip 10 is provided, inblank, with laterally extending wings 11 and 12 which are adapted to befolded along the dotted lines, as shown in Fig. 6, to provide a housinggenerally indicated by the numeral 13,

the top thereof being slightly inclined from its outer end. In theformation of the housing, the extensions 14 whichform locking tonguesare first bent upon their folding lines so that when the housing isformed, said tongues will assume the parallel and then inwardlyconverging or inclined positions shown in Fig. 4 of the drawing. rlhewing 11 isv then bent to form the side 15 of the housing 13 and thetop16 thereof, which operation will bring the locking tongues 14 in theposition previously described. The extremity ofthe wing 11 is then bentto form a U-shaped portion 17 which provides a longitudinal groove forthe reception of the extremity 18 of the lateral wing 12 which is alsobent to form an inverted U-shaped portion 19, as clearly shown inFig. 1. The interlocking joint formed by the extremities of the twowings 11 and 12 provides the other longitudinal side of the housing. Thewing 11 isprovided with an extension 20 opposite the locking tongue 14thereof which is bent to form a closure for the rear end of the housing13 after the other parts have been folded as just described.

The other end of the body portion 10 is reduced as indicated at 21 toprovide an extension 22, the extremity of which is folded along thedotted lines shown in Fig. 6 to form the oppositely disposed lockinglugs 23. In the formation of the lugs 23 the extremity 22 is firstfolded along the two innermost dotted lines on one side of the main bodyportion to form one ofthe locking lugs and then bent on the remaininglines to provide the locking lug on the opposite side of the bodyportion. Inwardly from the locking lugs 23 and adjacent to the inner endof the reduced extension 22, the metal is struck up to provide theinclined lug 24 which, when the seal is in locked position, forms aclosure for the outer end of the housing 13.

In practice, when it is desired to seal a car, one end of the seal ispassed through the usual staple on the door of the car and the end ofthe body portion provided with the locking lugs 23 is then inserted intothe housing 13. Said lugs will engage the locking tongues 14 and spreadthe samev apart until the inner ends of the lugs have passed the innerends of the locking tongues when the closure 2O will be engaged by thelugs and said tongues will, by reason of their resiliency, spring backinto their normal poY sitions and engage the inner ends of said lugswhereby further longitudinal movement of the locked end of the striprelative to the locking end thereof will be prevented. When the tongues14 assume their locking position, the lug 24 will be entirely within theouter end of the casing and the locking tongue adjacent to the inclinedsurface of said lug will engage the same and exert suflicient pressurethereon to cause the side opposite the inclined surface to engage theother locking Astrip lso that the parts will assume the position shownin F ig. 2 and the locking lug 24 form the closure for the outer end ofthe housing 13 and prevent any lateral movement of the locked end of thestrip relat-ive to the locking end of the strip.

From the foregoing description taken in connection with the accompanyingdrawing, it will be apparent that the invention provides a seal ofsimple construction, thus re` dueing the cost of manufacture to aminimum, and one which is eflieient in carrying out the purpose forwhich it is designed.

I claim l. A seal comprising a single strip of sheet metal bent at oneend to provide a housing, a closure for the inner end of said housing,locking tongues converging inwardly from the outer end of said housing,the other end of said strip being bent upon itself to provide lockinglugs on each side thereof adapted to engage said closure and the innerends of said locking tongues whereby f relative longitudinal movementbetween the ends of the strip is prevented, and a closure for the outerend of said housing formed in the strip adjacent said locking lugs andadapted to prevent relative lateral movement between the housing and theportion of the strip inclosed therein.

2. A seal comprising a single strip of sheet metal bent and folded atone'end to @opten of this patent may be obtained for ve cents each, byaddressing the Commissioner ei' Entente,L

provide a rectangular housing, a closure for the inner end of saidhousing, locking tongues converging inwardly from the end of saidhousing, the other end of said strip being intimately folded andrefolded together to form a substantially solid rectangular lockingblock for entering said housing, said locking block being of dimensionsto snugly fill the space within the housing between the innerend closurethereof and the ends of said tongues and to fill said space laterallywhereby relative movement between said housing and strip end will beprevented, the ends of said tongues engaging the outer end of said blockat each sideof the strip whereby to prevent withdrawal of the strip endafter insertion thereof into the housing.

3. A seal comprising a single strip of sheet metal bent and folded atone end to provide a rect-angular housing, a closure for the inner endof said'housing,` locking tongues converging inwardly from the end ofsaid housing, the other end of said strip being intimately folded andrefolded together to form a substantially solid rectangular lookingblock for entering said housing, said locking block beingof dimensionsto snugly fill the space Ywithin the housingbetween the inner endclosure thereof and the ends of said tongues and to fill said spacelaterally whereby relative movement between said housing and stripend'will be prevented, the ends of said tongues engaging the outer endof said block at each side of the strip whereby to prevent withdrawal ofthe strip end after insertion thereof into the housing, and a closurefor the outer end of said housing formed in the strip adjacent saidlooking block, said closure completely closing the outer end of saidhousing.
